[embodiment]
Please refer to shown in Fig. 1 to Fig. 3, bayonet connector 100 of the present invention can be welded on printed circuit board (PCB) 500, and in order to grafting electronic cards (not shown); Bayonet connector 100 comprise lengthwise insulating body 1, be immobilizated in the several conducting terminals 2 in insulating body 1 and be immobilizated in insulating body 1 at least one the grasping plate part 3 be fixed on printed circuit board (PCB).
Described insulating body 1 is provided with the two side 11 extended along longitudinally, the end walls 12 connecting two side 11 end along insulating body 1 horizontal direction, thus this insulating body 1 forms the central slot 101 extended along longitudinally (i.e. X-direction), for collecting electronic cards; Described insulating body 1 has protruded out knob of key 110 in central slot 101, for coordinating the corresponding groove (not shown) arranged in above-mentioned electronic cards, prevents electronic cards anti-plug.Described conducting terminal 2 is divided into two rows to be contained in insulating body 1, comprise the first terminal 21 inserting insulating body along the abutting direction (i.e. Y-direction) perpendicular to longitudinally, second terminal 22 that insert insulating body contrary to the first terminal 21 direction of insertion, described insulating body 1 has slot 101 central with this and is connected and several the first terminal accepting grooves 102 of accommodating above-mentioned two groups of terminals, second terminal containing slot 103, first, second terminal is arranged in two side 11 respectively, the first terminal 21 is provided with the first holding parts 211 be immobilizated in insulating body, extend from the first holding parts 211 and protrude into the first contact site 212 of central slot 101, the first weld part 213 outside insulating body is extended from the first contact site 211, be electrically connected for above-mentioned printed circuit board (PCB), second terminal and the first terminal similar, have the second holding parts 221, second contact site 222 and the second weld part 223.Described first contact site, the second contact site are upper positioned opposite in central slot 101 both sides at the vertical direction (i.e. Z-direction) perpendicular to longitudinally, abutting direction, to contact the relative both sides of electronic cards respectively; In abutting direction, the weld part of first, second terminal lays respectively at insulating body both sides, can reduce the area occupied on printed circuit.
Please refer to shown in Fig. 4 to Fig. 6, first holding parts 211 of described the first terminal 21 has the retainer 214 being contained in insulating body the first terminal accepting groove 102, the first location division 215 and the second location division 216 be disposed adjacent with retainer 214, described first location division 215 and the second location division 216 are interfered mutually with insulating body, and retainer 214 in the vertical direction is limited position by insulating body; When the first terminal 21 inserts the first terminal accepting groove 102, due to the both sides cell wall of the barb structure destruction the first terminal accepting groove that the first location division 215 has, can mutually interfere with insulating body and continue to move ahead, first location division 215 is provided with the rake 2151 acted on mutually with insulating body, insulating body makes the first terminal be close on the downside of the first terminal accepting groove to the reaction force that rake 2151 applies to move, and is conducive to guiding the first terminal smoothly and accurately insert; Described retainer 214 ensures that this first terminal accurately inserts and play can not occur on set direction, and the second location division 216 also has barb structure, is fixed in insulating body to interfere, and is conducive to that the first terminal 21 is stable is fixed on insulating body 1.In present embodiment, described retainer 214 is not interfered with insulating body 1 or is combined with low interfering edge, accurately inserts simultaneously, relatively can reduce Cat-in resisting force at guarantee the first terminal.
Second holding parts 221 of described second terminal 22 has main part 2210, three location division 224 thinner than main part, forms stepped, reduces destruction to insulating body at stable this second terminal of fixing simultaneously, 3rd location division 224 is interfered mutually with insulating body, when the second terminal 22 inserts the second terminal containing slot 103, 3rd location division 224 also has the barb structure of destruction second terminal containing slot both sides cell wall, mutually interfere with insulating body and continue to move ahead, 3rd location division 224 is also provided with the rake 2241 acted on mutually with insulating body, insulating body applies reaction force to this rake 2241, be close on the downside of the second terminal containing slot to make the second terminal and move, be conducive to guiding second terminal smoothly and accurately insert, corresponding, the cell wall 1031 of the second terminal containing slot 103 is stepped, match with stair-stepping second holding parts 221, because the 3rd location division 224 thickness reduces, in the second terminal stable position simultaneously, the thickness reducing bayonet connector is also conducive to.
As can be seen here, the rake guiding that bayonet connector of the present invention is arranged by first, second terminal, to realize accurately, to stablize inserting first, second terminal; And the segmental structure of the first terminal holding parts is also conducive to, and the first terminal is stable to be fixed and relatively can reduce Cat-in resisting force.
In sum, these are only preferred embodiment of the present invention, should not limit the scope of the invention with this, namely every simple equivalence done according to claims of the present invention and description of the invention content changes and modifies, and all should still remain within the scope of the patent.
